Although some species of fish are hard to breed in an aquarium environment, many kinds of the fish can without problems breed in captivity under suitable conditions. Large breeding of cichlids can lay lots of eggs at a time, however, most of the time, only a few fries live on and grow to maturity if left in community tanks. If you are serious about breeding cichlids, and if you choose to raise a giant range of cichlids to maturity, building up a cichlid fry tank separate from the breeding tank is a necessary step. Separate from other fish, your cichlid fry will be likely to survive. Read more to study different valuable recommendations on raising cichlid fry to maturity.
Breeding Cichlids
Raising freshwater aquarium fish is a beneficial and challenging experience. Read on to increase your chances of raising the fry to maturity.
When it comes to breeding fish, cichlids can be divided into two main groups by their breeding methods: one group contains mouthbrooders and the other group contains substrate spawners. Regarding mouthbrooders, the mating process is no different from other cichlid species. However, when the eggs are released by the female, one of the pair will put the eggs in the mouth and keep them until they hatch. In some cases, the female will collect eggs in her mouth, and the male will fertilize them. Once the eggs have hatched, fry tends to stay close to their parents as they grow, relying on them for food and protection.
Substrate spawning species of cichlid can be further divided into groups based on where they store their eggs. Some species spread their eggs over a wide area on substrate and plants while others store them on a flat surface. There are other species that dig a nest in the substrate and store the eggs directly into the nest. Just as breeding mouthbrooding species protect the eggs in their mouths, so will substrate spawners protect their eggs. During breeding, cichlid can become very aggressive and territorial in protecting their eggs and fry.
Nursery Tank
After your cichlids have spawned your first move should be moving the parent fish from the tank if the species you are breeding does not show any parental care behavior. Mouthbrooding species of cichlid and some other species actually care for their fry for several days (or longer) after they hatch. To determine if this is the case or not you may need to do some basic research. If you are able to determine that your cichlids do not typically care for their children it is best to move the adults from the tank as soon as spawning is complete.
When your cichlid fry hatch for the first time, they don't need much space-they just need a safe environment where they can spend their first days. In the first 5 to 7 days after hatching, the cichlid fry feed on the yolk sac residue, so no feeding is needed during this time. On the contrary, feeding the cichlid fry during this time will only cause the water quality in your tank to decline, because the food will not be eaten by these newly hatched fish. As the fry begin to mature, they can be moved to a nursery or rearing tank. This tank can be small, between five and ten gallons incapacity, and it should be sparsely decorated to make water changes easier. Use water from the breeding tank to fill it and equip the nursery tank with a quality aquarium heater and a sponge filter. It is important that filtration and water circulation be achieved in the fry tank, but you do not want to use anything powerful enough to hurt the fry.
After about a week, you can start making regular water changes, changing 10% to 20% of the water in the water tank, and adding fresh dechlorinated water. Start feeding your fry with protein-rich foods and live foods two or three times a day. Over the next few weeks, the fry should begin to grow and mature, and once they triple their original size you may move them to a grow-out tank - a larger tank where they can grow freely.
Grown Tank
Based on the number of cichlid fry you plan to keep, the size of a grown cichlid fry tank should be between 20 and 30 gallons in size. It's also a good idea to have enough heating, lighting and filtering equipment. Check the pH frequently and keep it between 7.5 and 8.5, depending on the type of cichlid you want to raise. Although many species can adapt to slight changes in water quality, young fry is likely to be very sensitive and may be harmed by sudden changes in pH or water temperature.
You can show your creativity more when decorating your growth tank-fill the bottom with some kind of dark substrate and give the fry enough place to hide. Use rocks and PVC pipes or clay to make horns and hoe in which your cichlids can hide in. You may also include some live plants like java moss or hygrophila to increase the oxygen content in your fry tank. When decorating your grow-out tank, be sure to leave enough open space for the fry to swim freely - keep the rock caves and piles concentrated in the corners of the tank so the middle remains open. If you continue to feed the fry a healthy, balanced diet you will see them grow fairly quickly.
Last but not least, raising cichlids and fry is a fun and rewarding experience for aquarium enthusiasts, but it also requires a lot of time and energy and extreme patience. In order to properly and correctly breed cichlid fry, you will need several additional fish tanks as the cichlid fry tank and the grown tank. You may even need to divide the fry into several different breeding tanks if some grow faster than others. Once your cichlids have grown to about two inches in length, you can consider putting a few of them into your community tank without overcrowding the tank or selling them to other aquarium owners.
